# Huberman Protocols: A DACH Take

Huberman's basics are solid; his specific numbers are often shaky. Morning light, sleep hygiene, and the training advice (Zone 2, strength, HIIT, daily movement) rest on well-established science. But signature figures like "11 minutes of cold per week" come from a small observational winter-swimmer study (Søberg 2021, ~16 people, water 1 to 9°C, not the cited 10 to 15°C), and the 250%-dopamine claim comes from a separate one-hour immersion study, not a 2-minute plunge. Take the principles, verify the specific protocols and supplements before copying them.

Light, sleep, cold, NSDR and training. What the evidence actually says.
